Lapierre Overvolt AM 7.8 800wh Grey 2025 Electric Mountain Bike

OVERVOLT AM 7.8

Leave your troubles at home. Set off for a ride on the Overvolt AM 7.8 Performance Line CX. This electrically-assisted all-mountain bike is the ultimate machine for discovering, loving and adopting the mountains. Thanks to its solid heritage, it is immune to the constraints of the bumpy trails found in mountain resorts.  At high altitude, its kinematics and handling border on enduro, with unique manoeuvrability and responsiveness.

The Mullet design (27.5-inch rear wheel / 29-inch front wheel) adds another dimension to mountain adventures. It complements the 170 mm of travel provided by the RockShox Zeb Base Rush RC fork, known for its reliability in every situation. By guaranteeing optimised grip on the rear triangle while retaining clearance on the front, this geometry contributes greatly to overall performance. 

New generation, new size

Bosch, an haute couture motor. This is how the new generation of super-powerful Bosch motors could be described. The Made in Germany label that is synonymous with quality has evolved in perfect symbiosis with the Overvolt AM. On the list of improvements included in this new generation motor, we note a more compact and lightweight system and improved connectivity. The motor block includes a new cell format for unprecedented responsiveness and durability! As a bonus, the ecosystem includes an 800wh battery for maximum autonomy.
